rlhis invention relates to improvements in shoe cleaning and polishing machines and its object is to `provide a machine of this class that is of durable construction, efficient and economical in operation.

With the foregoing and other objects -in view the invention consists in the combination and arrangement of parts to be hereinafter fully'described, pointed out in the appended claim and illust-rated in the accompanying drawings which form a part of this application and in Which- Fig. 1 is a longitudinal sectional View through the machine and is taken on line 1 1 of Fig. 2.

Fig. 2 is a top plan view of the machine, the dust pan being omitted.

Fig. 3 is an enlarged sectional detail view showing the belt and pulley drive arrangement. Fig. 4 is a vertical sectional vieW showing the actuating mechanism for the polish applying means.

Fig. 5 isa cross section on line 5-5 of Fig. 2 showing the polishing brush support mechamsm.

Figs. 6 and 7 are sections taken, r espectively, on lines 6 6 and 7-7 of Fig. 5, enlarged.

Fig. 8 is a detail ofa coil spring pulley belt employed.

Fig. 9 is a sectional detail view showing the dust receiving pan with support and control means therefor. f

Fig. l0 is a'vertical sectional view through the polish reservoir.. g

Like reference characters denote corresponding parts throughout the several views.

The machine comprises a frame of oblong shape and having the base 1 upon which are disposed theside Walls 2, 3 and end Walls 4, 5, a transverse partition 6 being arranged upon said base divides the frame into tWo compartments, one uponV each side of said partition. 'A platform 7 formed With a perforation 7 a recelves a circular perforate plate 8 supported upon a cleat 9 carried by the platform and forms a cover for this compartment, the other compartment being open at the top.

Upon the base 1 at about the center of the compartment 5, 6 is a stationary sleeve 10 through the base `sleeve 10.

and slidably encompassing the same is the l sleeve 11 formed. with `oppositely disposed slots 12 andterminating at its upper end in the flared vrace 13 provided with ball bearings l14 that support the grooved base '15y of the brush 16. A cord 17 extends through the slots 12in'the sliding sleeve and through per-V forations inthe stationary sleeve and has its ends secured to said sliding sleeve at points diametrically Vopposite eachother, said cord also passing through a perforation in a plunge'r 18 that extends through the platform 7, of the brush and into the A belt 19 engagesfthe grooved portion of the base ofthe brush and-passes over a pulley 20 supported by a bearing 21carried inthe frame compartment,said pulley 2O being operatively connected by the shaft 22 with A belt 25 connects the pulley 23 With either a pulley 26fast'upon the drive shaft 27 or With a pulley -28 loose 'upon said shaftwhich shaft is driven by lthemotor 29. v A belt 30 connects eithertheloose .pulley 28 or the pulley 31. fast upon the drive shaft 27 with a i pulley 32 fast upon'the brush shaft 33 that Vis connectedto another and similar .brush -shaft'34 by a crossed coil spring belt 35 thatruns over the pulleys 36A one ofwhich is fast upon each of the said brush shafts.

Each end of each brush shaftis mounted 38 y,formed in the Wall 4 andl in the partition 6, each carriage being connected by a return p spring 39 to a hook 40 at one end of the said recess, each carriage being connected alsoby a cord 41 that passes over a pulley `42, in said recess, through one of the lvertical recesses 43 in saidwall and partition to another carriage 44 operative in an enlarged portion 45 of the verticalrecess 43, the carriages 44, tWo'in number, being Connected by a bridgebar 46, the ends of vvhichvare tubular to receive the outer ends offV said carriages which `bear against expansion coil springs Y47 disposed in tion 48 to 'permit passage therethrough of an,

a pulley 23 supported by the bracket 24.

Vin a roller carriage 37 and said carriages are adapted to ride back and forth in the recesses inclined tubular post 49 secured at its inner end to the base 1 and terminating at its upper end in a shoe plate 50. A plunger 51 provided at its outer end with a shoe plate 52 is disposed in the post 49 and is engaged by a pin 53 carried by the bridge bar 46 and passing through a slot 54 in the post. The position of the post 49 is between the brush shafts 33, 34 so that the plunger 51 and shoe plate 52 will be disposed between the brushes 55, two in number, carried by 'said brush shafts.

A circular dust pan 56 isformed with an arcuate slot 57 through which the sleeve 11 extends to secure said pan movably to the base 1, said pan being provided with a handle 5S fulcrumed upon the' pin 59 to the base whereby said pan may be moved into and out of position beneath thebi'ush' 16. In the position beneath the brush it receives dirt falling therefrom and in its outer position the said dirt may be removed, swept out or otherwise disposed of. The pan is movable through a slot or cut out portion 60 in the wall 2 to provide Clearance.

An angular bracket 61 secured to the side wall 3 of the frame carries a reservoir 62, at its upper end, for liquid shoe polish which polish is introduced through the orifice 63 and which is ej ectedV through a valved orifice 64 opened by depressing the valve stem 65, the spring 66 serving said orifice closed. A rotary brush `67 is arranged beneath the reservoir 62 upon a brush shaft 68 journaled in said bracket 61and in a'bearing 69 and provided with a pulley 70 connected by belt 71, that passes through a perforation72 in sa-idwall 3, to pulley 74 Y fast upon the drive shaft 27.

This machine may be placed upon the'porch or in the receptionjhall of a dwelling or installed in shoe `shining parlors.- Iiifnse the party whose shoes are to be cleaned and polished tur'ns on the motor 29 and shifts the belts 25, 30 to the pulleys 26, Q3 thus driving the lrotary brush 16. He now places one foot upon the plunger 18 which raises `the said brush and the same rotating againstthe shoe cleanses it of dirtwhich falls into the pan 56 from which it may be removed as previously described. cleaned he repeats the operation upon the other shoe. He now shifts the belts 25, 30 back to the pulleys 23, 31 thus stopping rotation of the brush 16 and starting' up the brushes 55. Previous to this, however, he depresses the plunger causing polish to be Vapplied to `the brush '67 and Vso positions one shoe yat a .time that the said brush will ap ply thereto the polish. Y

He now 'placeson'e shoe upon the foot plate 52 depressing the v'same 'together with fthe bridge 46 which draws the brushes 55 toward each other and causes them to rotate against the shoe, the brushes rotating toward Veach other 'due to 'the vcrossed belt 35that rotates the brush upon to yieldingly retain the shafts 33, 34. When the shoe is removed from the foot plate it will rise again due to the action of the springs 39 and e7 and after both shoes are thus polished the motor is shut off thus stopping the mechanism.

What is claimed is:

In a shoe cleaning machine, a perforated housing, a rotary brush mounted for movement into and out of the perforation in said housing, a stationary sleeve upon the base of said heusing having perforations near its top, a movable sleeve encompassing said stationary sleeve and directly supporting said brush, a plunger within said sleeves and projecting above the perforated portion of the housing, and a cord passing through Said perforations and connecting the lower ends Vof said plunger and movable sleeve tofraise depression of the plunger. ln testimony that I claim the foregoing as Vmy own lhave hereto aiiiXed my signature.
